i'd suggest calculating your ppms of what you provide - with and without the booster for bloom. Ensure you aren't going extremely high in p or k.
i have a nutrient spreadsheet with instructions linked in my profile. it is verified to work using a different online calculator for %W/W listed ingredients too. US standards for p and k.
upto 10 products and can be scaled to any size, if you read the instructiosn how-to. E.G. i wouldn't go higher than 100PPM P or 200PPM K. If you provide near that, you'll just cause major problems in plant if you add more. Thos enumbers are a big grey area, for what it is worth... more a guideline.. your pH wil have a major say, as well as concnetration of other elements, as far as what is "right" for you.
